Definitions

  • SRP Spreading Resistance Probe
  • a semiconductor element is herein cut obliquely and the resistance between in each case two probe points placed on the surface is measured. These probe points or conductors are placed at an interval of approximately 15 to 50 am. The angle of inclination is in the region of several minutes to several degrees. The conductors are stepped over the obliquely cut portions with a step size in each case of 2.5 to 5 am.
  • the resistance measurement can take place with both direct voltage and alternating voltage.
  • a problem here is the deviation in the contact resistance between conductor and semiconductor element.
  • the point of the conductor is accurately polished, which can sometimes take days, until the contact resistance on a calibration sample reaches a predetermined value. Even after the time-consuming calibration of the points of the conductors the deviation in the contact resistance results in inaccuracies in the measurements.
  • the present invention has for its object to provide a new method wherein the accuracy of resistance measurements on a semiconductor element is considerably improved.
  • the invention provides a method according to claim 1.
  • Fig. 1 and 2 are measured using an AFM arrangement (Atomic Force Microscopy).
  • a semiconductor element is movable three-dimensionally with piezo-crystals, a first of which adjusts the pressure or distance of a conducting needle relative to the semiconductor element, while two others enable a movement over the surface of the semiconductor element.
  • a laser beam is directed onto the contact point of the conductor and the semiconductor element. The reflection of the laser beam is picked up in a photodiode, wherein the output of the photodiode is fed back to the first mentioned piezo-crystal.
  • Fig. 2 shows measurements on a substrate with a comparatively smaller resistivity p - 0.0084 Q.cm. Different measurements are indicated with different curves in fig. 2 and show an approximately linear relation (1 3 and 1 4 ), wherein the angles of slope of the lines (1 3 and 1 4 ) are dependent on the applied pressure between conductor and semiconductor element.
  • this conductor penetrates through a thin oxide layer which in practice is almost always present on the semiconductor element.
  • the pressure force can be held very constant because of feedback to the first mentioned piezo-crystal.
  • the conductors are moved over the surface for measuring the resistance or conductivity along the sloping surface, wherewith the resistance at different depths in the semiconductor element becomes known.
  • An important novel feature of the method according to the present invention relates to the possibility of measuring either with DC current and/or voltage, or AC voltage or current.
